Wawa:
That ebay link, who knows what it is.
Probably a photo transistor.
Photo transistors are a lot faster than an LDR.Sensor in a glove?
The laser has to shine exactly on the sensor, and the sensitive area of a photo transistor is a lot smaller than an LDR.
Could work as a beam break sensor though.
Leo..
The sensitivity area of the LDR is, in fact, a lot better than the photo transistor. In my project I don't have any structure above the lasers so I can't use as a "beam break sensor". That's why I want to put the receiver in a glove.
The common laser harps have a sensor in the floor, and the reflected laser triggers the sensor. I don't want to do like this because I want to minimize the interference of ambient lights.
Do you know any photo transistor with high sensitivity for visible light and high speed response?
